Definitions

  • the invention relates to a process for making ice cubes, comprising moving a tank with water into an uppermost position around downward directed protruding parts, refrigerating the protruding parts, when the tank is in said uppermost position so that ice is formed around said protruding parts, moving said tank from its uppermost position to a lowermost position by supplying water to it, after sufficient ice has been formed around said protruding parts, and slightly defrosting the ice formed around said protruding parts so that said ice falls off, after sufficient ice has been formed around said protruding parts.
  • this microswitch has as a consequence that means for opening and closing the water supply pipe open this pipe.
  • the tank becomes heavy enough to move from its uppermost position to its lowest position. But before this tank has reached its lowest position, the protruding parts are heated by heating fluid so that the ice cubes come free from these protruding parts. The refrigeration mechanism no longer cools the protruding parts in the meantime.
  • the filled tank in its lowest position, allows water to flow away through an opening. After sufficient water has flowed away through the opening, the tank with its contents will have become sufficiently light to rotate upwards again. During this upward movement the defrosting is terminated and cooling fluid is again sent through the evaporator. But before the tank has reached its uppermost position a small amount of water is again allowed into the tank, however, not sufficient to prevent the upward movement of the tank.
  • the invention has the purpose of remedying these disadvantages and to provide a process for making ice cubes of the above mentioned type whereby the ice cubes have almost the same size and the reduction of the production of ice as a result of ice cubes which remain hanging on the protruding parts is avoided, regardless of the manner in which the thickness of the ice formed and therefore the stopping of the cooling and starting of the defrosting is determined.
  • an upper grid hingedly mounted around a horizontal axle is pushed up, by the movement of the tank from said lowermost position to said uppermost position, into an uppermost position in which position it is located between the protruding parts so that, when the ice is formed around said parts the grid is situated above the ice cubes and cannot go down as long as all the ice cubes have not fallen off, and in that the defrosting is only stopped and subsqequently the refrigerating of the protruding parts restarted after said grid has hinged downwards from its uppermost position and thus after all the ice cubes have fallen off.
  • the control that all ice cubes have fallen off is effected in a very simple mechanical manner. As long as all ice cubes have not fallen off, the new cycle for making ice cubes cannot start again and the defrosting continues. The duration of the defrosting can therefore be determined by the ice cubes falling off and therefore in a very simple and certain manner.
  • the water supplied for moving the tank from the uppermost position to its lowermost position is at the same time used for slightly defrosting the ice formed around said protruding parts.
  • defrosting with cold water can be effected without problems and namely with the cold water that must be supplied to fill the water tank.
  • warm gas is used for the defrosting, the temperature of which is controlled by a thermostat.
  • the invention also relates to an apparatus specifically designed for carrying out the above mentioned process.
  • the invention thus also relates to a device for making ice cubes which contains a frame, a refrigeration mechanism which in turn has a compressor, a condenser, an expansion element and an evaporator with downward directed protruding parts permanently mounted on this frame, means to slightly defrost the iced formed around the protruding parts and to cause it to fall off, a water tank that is movably mounted on the frame, a water supply pipe which exits above the tank, means to move the tank from an uppermost position around the above mentioned protruding parts to a lowermost position and vice versa, which means comprise the means itself to open and close the water supply pipe, and organs which controls the aforementioned refrigeration mechanism and the above mentioned means to move the tank, characterized in that it contains an upper grid that is hingedly mounted around a horizontal axle to the frame and extends in the uppermost position of the tank on the top just between the downward directed protruding parts of the evaporator so that, when the ice cubes have been formed around these protru
  • the evaporator contains a number of fingers directed downwards of which the uppermost extremities, on the one hand, are mounted between two parts of the refrigeration pipe of the evaporator, and, on the other hand, are situated above these parts in a defrosting liquid supply.
  • the device has a storage tray for ice cubes which is situated under the water tank and a feeler grid that is mounted on top of the storage tray, while the organs which control the refrigeration mechanism and the above mentioned means have a switch which is controlled by this feeler grid to switch off at least the means for moving the tank when sufficient ice is present in the storage tray.
  • the device for forming ice cubes contains a frame 1, 2 that principally consists of two upright walls 1 and transverse connections 2, 30 and 58 between which walls 1 a water tank 3 is movably mounted between an uppermost position presented in the figures 1 and 2 and a lowest position presented in the figures 3 and 4.
  • This water tank 3 is hingingly suspended from the frame 1, 2 by means of two arms 4 each of which is connected with a hinge point 5 hinged with an upright wall 1 of the frame 1, 2 and each is hinged to a hinge point 6 with a small plate 7 fixed to a side wall of the water tank 3.
  • the arms 4 are extended past their hinge points 5 and a cylindrical counterweight 8 is fixed between their extremities.
  • the movement of this arm 4 is restricted by two of the above mentioned transverse connections 2 which consequently at the same time determine the uppermost and lowest position of the water tank 3.
  • a directional arm 9 which, on the one hand, in a hinge point 10 near the uppermost edge of the tank 3 is connected with the above mentioned small plate 7 and, on the other hand, is attached to an axle 11 which is mounted on bearings in an upright wall 1 and also forms a hinge point for the arm 9, prevents the complete tipping over of the tank 3.
  • the arms 4 and 9 form a right angle with their hinge points 5, 6, 10, and 11. This quadrangle is such that the water tank in its uppermost position forms another angle with the horizontal surface then in its lowest position.
  • An opening 12 is cut away in an upright wall of the water tank 3. This opening 12 can be adjustable, so that the speed with which the water flows out of this opening may be predetermined.
  • the difference between the angles that the water tank 3 in its uppermost and lowest position forms with the horizontal surface, is such that in the lowest position water can flow away out of the tank 3 through the opening 12 until this tank with its contents has become sufficiently light to move back upwards to its uppermost position under influence of the counter weight 8. In this uppermost position the opening 12 lies above the water level.
  • the downward movement of the water tank 3 is effected by the supplying of water into this tank in its uppermost position.

  • An electric valve 14 is mounted in this water supply pipe.
  • the water tank 3 In its uppermost position the water tank 3 is situated around a number of downward directed solid copper fingers 15 which extend with their extremities into the water in the tank. These fingers 15 are part of the evaporator 16 of the refrigeration mechanism.

  • the fingers 15 of each row are placed with their uppermost extremities contained between a serpentine refrigeration pipe 23 of the evaporator 16. These parts of the pipe 23 are partly sunk into the fingers 15 in order to effect a maximum transfer of cold from the refrigeration medium that flows through the pipe 23 and these fingers 15.
  • a duct 24 is attached on top of the two parts of the pipe 23 which extend along a row of fingers.
  • the uppermost extremities of the fingers 15 extend through the bottom of this duct 24.
